Abstract
A scanner has a housing, and a glass piece positioned over the housing and covering portions of the interior of the housing, with the glass piece adapted to support an image to be scanned. The scanner further includes a sensor positioned inside the housing below the glass piece, and a light source positioned inside the housing below the glass piece in a manner to direct a light beam at the glass piece so that the light beam is reflected off the glass piece and is received by the sensor to capture the image to be scanned. As a result, the entire image is captured at the same time by the sensor.
Claims19
A scanner having a housing, the scanner comprising:
- a glass piece positioned over the housing and covering portions of the interior of the housing, the glass piece adapted to support a stationary image to be scanned;
- a stationary sensor positioned inside the housing below the glass piece;
- and
- a light source positioned inside the housing below the glass piece in a manner to direct a light beam at the glass piece so that the light beam is reflected off the glass piece and is received by the sensor to capture the image to be scanned.
A scanner having a housing, the scanner comprising:
- a glass piece positioned over the housing and covering portions of the interior of the housing, the glass piece adapted to support a stationary image to be scanned;
- a stationary CCD or CMOS sensor positioned inside the housing below the glass piece;
- and
- a light source positioned inside the housing below the glass piece in a manner to direct a light beam at the glass piece so that the light beam is reflected off the glass piece and is received by the sensor to capture the image to be scanned.
A method of scanning an image on a stationary document, comprising the steps of:
- a. providing a scanner having:
- a glass piece adapted to support an image to be scanned;
- a stationary CCD or CMOS sensor positioned below the glass piece;
- and
- a light source positioned below the glass piece;
- b. directing a light beam from the light source at the glass piece so that the light beam is reflected off the glass piece and is received by the CCD or CMOS sensor;
- and
- c. capturing the entire image at the same time at the CCD or CMOS sensor.
